Gameplay If We Could Extend Routes In The Editor Where Would They Go To

Hi guys if could edit routes that already been made like on sale on steam and could extend them where you all extend them too like here are some ideas/list

Like extend Bakerloo Line to Watford Junction and Stanmore
Extend South Eastern Hight to Dover Margate and Ramsgate or go London with the Dartford Loop lines
Extend ECML to ever York Leeds or South to Kings Cross
Remake Great Western Express and extend it to like Oxford Swindon or even Bristol

If you have any ides for route extensions let me know

 

Probably adding some branch lines into Salzburg-Rosenheim (Traunstein-Ruhpolding for example) or extending S-Bahn Vorarlberg into Switzerland

 

One of the easiest expansions i think would be Dresden Neustadt - Dresden Flughafen. It already exists and is VERY detailed. The Berninaline to St. Moritz would be doable, the Terrain and the Tracks already exist. Or, on Kassel-Würzburg to Lohr, over the Old Route and over the SFS.

 

Extend the East Coastway to Hastings and Ore
